Base Rock Turning Green?

[Cutiewitbooty]

I have never bought base rock before, only live. Well I bought some baserock and it's truning bright green, am guessing it's some sort of film algae, but it's only growing on the baserock. Is this normal untill the coraline takes control?

Here is a pic, the peice on top is live.

Looks like mine. My LMB loves it.

My tank has the same stuff on my base rock, and in some of the less coralline covered parts of my live rock.

bump, anyone else?

 

[gman0526]

It's normal on base rock since it's loaded with PO4.

My baserock had the same thing for a while...now, I can't tell the difference between the base and the live.

well I don't beleave it is loaded with PO4....but that algae is one of the fastest to grow. So it is normal because nothing else is on the rock to compete with it. Just let it run its course.

thanks, i guess i'll just have to wait it out

 

[Cutiewitbooty]

here is a full tank shot, you can really see the green base rock lol

 

[stingers81]

hey that green rock looks kinda cool...how long have u had it in there for?

 

[Cutiewitbooty]

a couple weeks, here is a pic when i first got it, as you can see it wasn't green then lol

i like that setup. great rock structure. also, is that a 150watt or 250watt MH light?

 

[Cutiewitbooty]

150 watt, but i wish i had gone with the 250, but i can upgrade it as long as i buy a new ballast. But as of right now i have over 11watts per gal, so i can keep alot of stuff. The only reason i want 250watt is because the tank is 20" deep.

 

[The Reefer91]

i see. i'll be using 3 400watt bulbs over my 180g when i set it up. pretty bright even though it's 150watt. i don't think you need to change for coral, but for looks you might. it's a matter of taste

 

[Crazyfingerz]

i have that same problem, but it looks good IMO, once it doesnt harm my fish it can stay.

 

[bunzaroo]

My tank has been cycling now for 5 weeks with dry Marco rock and I have the same bright green algae. I cooked the rock for 2 months in a dark container prior to setting up the tank.

doesnt coralline start out green?

 

[elegance coral]

The algae is Ostreobium, and like the others have said, it's very common in bare calcium carbonate rocks. Just do your best to export phosphate, and the coraline should take over.

doesnt coralline start out green?

Green coraline is pretty common. Especially in younger tanks. It grows differently than Ostreobium though. Coraline starts from small specs and spreads out in all directions, almost evenly. You end up with a bunch of little circles of coraline that just keep getting bigger. Coraline also grows on the surface of the rocks. Ostreobium grows much differently. It actually grows within the rock. You can start out with white rocks, and it will invade all the bare calcium carbonate, that's exposed to light, and turn it a light shade of green. If phosphate is abundant, the rocks will get darker and darker green. Typically, the phosphate is bled off the new rocks and out of the system. Then other organisms, like coraline, out compete the Ostreobium and it goes away.

its normal, mine did the same things a long time ago. control you nutrients, and your rock definetly does not leach out PO4 unless you did not wash it well.
